Just ordered the SX2 base from LMS to replace my current x2 base. Instead of the Y axis 4", it will give me 5" in the Y axis. What size ball screw will I need for the new SX2 base? I called LMS and they said the regular Y axis screw for the X2 base measures total 10" with a 7" thread length. Would this mean that I would need the exact length ball Screw? I already have the complete cnc fusion cnc kit#2 on my X2, so I am only in need of the longer ball screw. Cnc Fusion says they use 5/8" x .200 pitch ball screws. Does anyone know the exact length ball screw needed? I'm sure I can just cut a ball screw also, so does anyone know where I can purchase a precise brand ball screw somewhere on the net? Thank you gor any help as I have a job coming up and am in need of this info to set up the new SX2 base and get started.
